Bathroom Remodel Cost Calculator
Total cost from fixture selection and layout changes.
About this calculator
This calculator prices a bathroom remodel from the ground up by itemizing exactly the components you specify, rather than applying a flat per-square-foot rate. Tile cost is calculated from your floor and wall square footage combined, multiplied by a per-square-foot rate that depends on material choice ($6 for ceramic, $10 for porcelain, $18 for natural stone). Fixture costs are toggled individually: a toilet replacement adds a flat $350, vanity replacement scales with your chosen scope level ($600-2,500 depending on tier), and shower/tub type carries its own cost from $800 for a tub-only setup up to $3,500 for a walk-in shower. Plumbing has a base cost driven by scope level, plus a $3,500 penalty if you're relocating rough-in lines — historically one of the most expensive line items in any bathroom job because it means opening walls and possibly the floor slab. Electrical and finish work (paint, drywall repair) round out the materials subtotal, each scaled by scope level from cosmetic refresh to upscale.
Labor is then calculated as a percentage of that materials subtotal — 40% at the cosmetic tier rising to 50% at upscale — reflecting the well-documented fact that bathrooms carry unusually high labor costs relative to materials because of tight working spaces, waterproofing requirements, and the number of trades that have to sequence through a small room. A contingency percentage (10% by default) is applied last to account for the unknowns bathrooms are notorious for: water damage behind old tile, subfloor rot, or outdated wiring discovered once demo starts. The output includes a full cost breakdown by category plus a cost-per-square-foot figure. Because bathrooms are the highest cost-per-square-foot room in most homes, small scope decisions — natural stone versus porcelain tile, or relocating plumbing versus keeping the existing layout — swing the total substantially, so it's worth running a few scenarios before committing to a final scope.

How to Use This Calculator
- Enter the bathroom floor area in square feet and select scope level (cosmetic, mid, or full gut).
- Enter tile floor and tile wall square footage and select tile material tier (ceramic, porcelain, or stone).
- Toggle fixture upgrades (toilet, vanity, shower, tub) to include in the estimate.
- Review total cost with the breakdown: tile, fixtures, plumbing, labor, and contingency.
- Adjust finish level or scope to find a budget that meets your goals.

Frequently Asked Questions
Why is labor calculated as a percentage of materials instead of its own line item?
The calculator applies a labor rate of 40% at cosmetic scope, rising to 45% at mid-range and 50% at upscale, multiplied against the materials subtotal. Bathroom labor genuinely tracks with material complexity — better tile and fixtures need more skilled, slower installation — which is why the rate itself climbs with scope rather than staying fixed.
Why does relocating plumbing add a flat $3,500 regardless of scope level?
Rough-in relocation is priced as a fixed $3,500 penalty on top of the scope-based plumbing base cost ($800-2,500), because moving supply and drain lines typically means opening walls or the floor slab no matter how upscale the rest of the remodel is — the cost is driven by the labor of relocating pipe, not by fixture quality.
How is tile cost calculated if I enter floor and wall square footage separately?
The calculator adds your tile floor and tile wall square footage together, then multiplies that combined total by a single per-square-foot rate based on material choice — $6 ceramic, $10 porcelain, or $18 natural stone — so floor and wall tile are priced identically per square foot regardless of which surface they cover.
Why does vanity cost include both a fixture price and a separate install price?
The vanity line item bundles a fixture cost and an installation cost that both scale with scope level (for example $600 fixture plus $1,200 install at mid-range), reflecting that a nicer vanity usually also needs more careful installation — leveling, custom countertop cutouts, plumbing tie-ins — not just a higher price tag on the cabinet alone.
